# Micro-timer
This crate exposes a simple procedural macro that logs you how much time was spent during each call of the function it wraps.
## Installing
In ``Cargo.toml``:
```toml
[dependencies]
micro-timer = "0.1.2"
log = "0.4.8"
```
The community-standard ``log`` crate is used for output. In reality, since procedural macros don't have hygiene, you could define `log` as being anything that has the same interface as the `log` crate.
## Usage
```rust
use micro_timer::timed;
/// Expose the `log` crate as `crate::log`.
use log;
#[timed]
fn my_func() {
// code here
}
fn main() {
// Use any standard logger you want.
// In this case, we're using `simple_logger`
simple_logger::init_by_env();
}
```
## Result
```bash
$ RUST_LOG=trace ./my-program
2020-02-27 14:27:01,097 TRACE [my_crate::my_module] Duration of `my_func`: 2.024734ms
```
